Dear experts, Please note that I’m considering ET-200M with redundant power supplies in S7-412H configuration and I’ve a few questions on AI & DI cards. Can someone please advise what are the wiring connection details · at terminal 1/11 and 21/40 for 6ES7321-1CH00-0AA0 (16 CH DI module). Will it need to be +24Vdc and 0Vdc respectively? · at terminal 1/21 and 20/40 for 6ES7321-1CH00-0AA0 (16 CH DI module). Will it need to be +24Vdc and 0Vdc respectively? Attached manual doesn’t show this. Attachment6ES7331-7NF10-0AB0 AI.pdf (130 Downloads) |
